Simulation-based microstructure prediction
The simulation of material behaviour is an important tool in process design. A model developed at Fraunhofer IWM allows predicting microstructure evolution during wire manufacturing. A simulation program makes the model available for practical application.

Fig. 2: Application of the material model to the hot rolling of steel: The variation of grain size and precipitation as well as their effect on the mechanical properties are predicted throughout the entire process chain. © Fraunhofer IWM
Fig. 3: Calibration of the model for a steel using compression tests and metallography. The calibrated material model reproduces the test results very well and can now be used to predict the material behaviour. © Fraunhofer IWM
